'1 0 aw wnom it may concern Be it known that 1, JAMES J. FARRING- TON, a citizen of the United States. residing at, Philadel hia, in the county of Philadelphia, and tate of Pennsylvania have in vented certain new and useful Improve-- ments in Vehicle-Jacks. ot' whirh the following is a specification.

One object of my invention is to pro ut' a vehicle jack which can be readil fjtltl ul as a permanent fixture on a which" sin-ll for example as an automobile and hen not do sired for use will be in such position lhui it will be clear of the roadway but when lesired for use can be readily moved inlo position toraise thevvhicle wheels out of a rut or above the surface of the [mull Another object is to pro vide my improv d jack with a wheel which will serve as an auxiliary rotatable support for the vehicle so that when. brought into eug'ag mniont. with the roadway or a board placed upon the roadway, it will serve to lift the veliiwle wheel ont o'f a rut or soft spot in tho roml way and will serve as rotatable supporting means for the vehicle to permit the vehicle to be moved into another position until said vehicle wheel has reaehetl a position over a hard portion of the roadway, otter whirh the jack wheel can he moved to permit said Vehicle Wheel to again engage the roadway.

A still further object is to make'rny inrproyed jack of a strong and durable coir stnrction and so that it can be easily and quickly attached to a vehicle.

These objects, and other advantageous erlds which will be described hereinafter, l attain in the following manner, referent-e being had to the accompanying drawings in which- Figure -1 is a rear elevation. of an aunt mobile showing the same equipped with two of my improved jacks, one adjacent each driving wheel. and also illustrating one of the jacks having lifted one of the vehicle Wheels out of a soft spot or rut in the roadway and providing a rotatable support so that the vehicle can be moved by the 'pro gelling means into another position on the roadway,

" 'Fig. 2 is an enlarged sectional plan view taken on the line 2-2 of Fig. 1.

Fig. 3 is an enlarged fragmentary elevation taken on choline 3-4-3 of Fig. 2,

Fig. 4 is a side elevation of Fig. 3, and Fig. 5 is a fragmentary Front elevation which, extends through an aperture of Fig. 2 with the cover plate of the casing removed.

The hou ing: ll is preferably flattened as slwwzu of lo am! the plates ill have col-rt spun-ling inner lint portions 17 (see Fig. ll for engaging said flat portions of the housing s as lo prevent rotation on the housing wh rl the plat s 13 are secured in position.

A hollow partition l l extends from top to bottom of the (:asin a l2 and provides a }ius sg0\\'ay l for a jar-l; lifting rod 20, soul lilting rod being made of heavy strong metal and ineludinn on one side a toothed grcarriuraging rack Bi and on the opposite sidr u pawl ratchet ruol-r 22, said racks extending; in the direction of the height of the look lifting rod 20. as clearly shown in Figs 2 to at inclusive.

The casing 12 provides a bearing for an operating shaft 2 whioh has secured to it within said easing, a gear wheel 24 which meshes with a larger gear Wheel 25 on a rounter shaft 26, said counter shaft having a hearing: in said casing 12. The counter shaft has a second gum wheel 527 secured thereto and of" smaller diameter than the gear wheel .25 and this gear wheel 27 meshes with a larger gear Wheel 28 on a sleeve 29; said sleeve being loosely mounted on the operat' ing shaft 23. The slervo .39 also has a small gear wheel or pinion 30 secured thereto 31 in the hollow partition 18 and engages the teeth of the rack 21. It is thus obvious that by rotating the operating shaft 23, the jack lifting rod 20 can he raised or lowered according to the direction of rotation of said operating shaft. This operating shaft is preferably provided with an angular end 32 which projects through the (over plate portion of the losing 12 and may be engaged by a crank lever or handle (not illustrated) whereby the jack lifting rod can be manipu- 'weightecl hilntlle lated. A detent pawl 34 is pivotally eonneeted to the bottom of the casing 1:2 and operatively engages the teeth of the ratchet rack 22 for preventing relative movement in one direction between the easing: l2 and jack lifting rod 20. The pawl 3 has a which normally holds the )awl in engagement with the teeth o l the rate of, rack 22 and when the pawl is to be released 1| om the rack 22, the weighted handle 35 (an be moved upwardly inl'o mlgagement with a spring" relainingwlip ill; w ieh is secured to the bottom of the (3;\Fi-

An auxiliary; supporting roller or wheel 35! is supported (L?! the axle 38 between [he lorrations al llh lower end of said lifting rod 2 During the normal operation of thh uhi' cle, the lifting rod 20 is in a raised position such for example as shown al lhe riphl hand Side of Fig. 1. ll either of tho j'l 7 ing wheels for example, should sink into a rut so that the vehicle would not he Inowih it is quite an easy limiter to more the incl; lifting rod 20 downwardly into engagement with the roadway or preferably to plum: a board, such as shown at 40 in Fig l, (liraily under the lifting rod. 20 and then more said lifting rod 20 downwardly until the auxil iary wheel 39 engages the top of the board 41). This can be done by turning the operating: shaft 23 and a continued turning of said ope-i ating shaft 23 will cause the vehicle ilriv ing Wheel to be lifted out of the rut such as shown at Q1 and the vehicle will he sup ported jointl by the opposil e driving: wheel and the anxi iarv Wheel By starting the engine of the vehicle, the driving wheel whieh is in engagement with the ground will .in Horni has l ven zoom? er move the Vtl'llLl lorwi'owlly and the auxiliary wheel will roll along: the hoard 4.0 an 45 til the driving) \i'loll hirl] hail lawn r-ltuvlc wild or hard portion of the ror'olwuy.
